Question

multiple choice question
na⁺ can be reabsorbed along the entire length of the nephron tubule with the majority being reabsorbed in the
o ascending limb of the nephron loop
o pct
o dct

Explanation:

The proximal convoluted tubule (PCT) is responsible for reabsorbing a large amount of substances including \(Na^{+}\). It has a high capacity for reabsorption due to its brush - border epithelium which increases the surface area for reabsorption. The ascending limb of the nephron loop and DCT (distal convoluted tubule) also reabsorb \(Na^{+}\) but in smaller amounts compared to the PCT.

Answer:

PCT
